Siphon tubes are needed for draining carboys, kegs, and other vessels that lack a valve. All our siphon tubes feature a curved top, and a sediment avoidance fitting at the bottom so they can rest on the bottom of the carboy. We offer stainless steel and plastic siphon tubes. Stainless steel siphon tubes feature a larger interior diameter and a sturdy spring-type sediment avoidance end (that will not come off) for faster flow. Our stainless siphon tube will empty a 5 gallon carboy in approximately 6 minutes. This 24” siphon tube is ideal for draining 5 and 6 1/2 gallon carboys. This fits 3/8" tubing, see our item E04.
